'Protocol vialation' exception in Oracle JDBC driver.

[Mike Freider]

I have some stored procedure wich has 3 'in' and 2 'out' parameters (long
and number(38)).
At some point I got strange exception:

exception caught: java.sql.SQLException: Protocol violation

The intersting feature is, what with other (in) arguments
and if I'm calling it from SqlPlus-monitor it returns exactly
what it should but NOT in java program.

If somebody know something about it, please help.
